OZONIZER.

A Tofall whom it may concern:

Be it known that I, ErrmAiM D. Kiers,

i' a citizen of'the United States, residin 1n sion,

the city, county, and-State of New ork,

have invented certaln new and useful Im;k provements in Ozonizersg. andI do hereby declare the followin j to be a full, clear, and

exact description o the inventionsuch as will enable others skilled in'the art to whichy it appertains to make and use the same.

This invention relatesl to ozonizers of the type employing a dischargeof a-high tenelectric current across a narrow gap between twoelectrodes. The object of the invention is to provide an improvedconstruction for an ozonizer of this type whereby simplicity'ofconstruction, ease of assemblage and low cost of manufacture areattained, "and in which provision is made for the circulationof air insuch a way as to guard a ainst over-heatin paratus. T e invention is usel in'ozonizers for various purposes, but is of special utility inmedicinal apparatus, including an ozonizer and a receptaclev for asubstance like pinene, with which ozorle combines to form a pineneozonid vapor.

I have illustrated the preferred embodiment of the invention in theaccompanying drawings, in which Figure 1 is a central,

vertical section of the ozonizer; Fig. 2 is a j plan view, and Fig. 3 isa transverse section on line 3-3 o-f Fig. 1f

Referring to these drawings, the ozonizer is built up upon a tube 4which may lbe a tube of metal such as aluminum servin as oneof theelectrodes of the ozonizer. T de# sired, however, this tube may be madeof some moldable, insulating material such as bakelite and may haveasheet of metal applied to the interior thereof. The tube, whether ofmetalor of insulating material, is provided with a lflange 5 at itsupper end which rests upon a support 6 to sustain the entire ozonizer inposition.` The lower end of the tube is open lbut the upper endis closedby a disk 7 of insulating material, preferably glass. This diskbears-upon the upper surface of the flange 5Ion tube 4 which flangebears uponthe upper surface I a ring 8 of insulating material is mountedupon the support 6 as shown, such size that it fits snugly within the 8.

Within the tube 4 is a glass cylinder 9, on the interior of which isametallic :film or of the ap.-

and the glass disk 7 is of coating l0.- This cylinder or` bottle ismounted within the tube 4 with its cylindrical wall separated from thewall-of the tube by a narrow space which may be about onesiXteenth of aninch wide. To facilitate accurately positioning the cylinder 9 within ythe tube 4, the latter is provided with a plurality of internalprojections or spacers 11. The lower series of spacers 11 coact with thelower-closed end of the cylinder 9 so `as to limit the downward movementof the cylinder through the 4tube 4 and both series ofv projections 11serve to position the cylinder Y accurately so that it is concentricwith the tube 4. The narrow space between the cylindervand tube istherefore of the same width at all points and the projections 11 of thetwo series are spaced yapart so that they do not restrict the flow ofair through this nar-` row space between the tube and cylinder.

The glass disk 7 serves as a closure for the upper end of the tube 4.The end ofthe cylinder@ adjacent to this closed end of the tube is open,as shown in the drawing. Y The opposite end of thecylinder is closed, as

stated above, and the end of the tube adja-.

cent to this closed end of the cylinder is open. Provision is made forsupplying air to the interior of the cylinder at a point adjacent to theclosed lower end of the cylinder. For this purpose a metallic tube 12 isprovided passing through a central opening in the glass disk -7 andextending down entirely throughthe cylinder 9 to a point adjacent to theclosed lower endvthereof. Provision ismade for guarding against theescape of air around the tube l2 at the point where it passes throughthe disk 7. `This is preferably done by making thetube 12 in sie twoparts which are joined together by coacting threads at this valve beingprovided with an operating handle 17. The tube 4, preferably made ofaluminum, constitutes one electrodeof the ozonizer. Electricalconnection is made to itl preferably b providing a leaf spring 18 in arecess in t e support 6 so that the end of the spring will be engaged bythe ange 5 on the tube 4 'when the tubeY is inserted in position. Thisspring 18 has a stud 19 on it n andadjacent to them are handles 255by, Y.whlch. the rmgl may berotated about its '18,.- depresses the latter, 50

1 lowered through adapted to be engaged byla suitable con- 'nectingdevice on the end of the wires eX- tending from the source of supply.The other electrode consists of the film or coating 10 of metal upon theinterior of the glass cylinder or bottle 9; rlhis lm maybe a ilm ofmetal applied' to the interior of the cylinder in the form of a paint.Preferably, however, the film consists of a thin sheet of metal, asaluminum., rolled to a cy?A lindrical form and then inserted withintheopen end of the cylinder 9. The spring tension of the metal willserve to hold the sheet in position within theA cylinder l 9 closelyagainst the glass wall of the cylinder. Electrical connection is made tothis film or sheet 10 through the metal tube 12. For this purpose aspring arm 20 is secured upon the tube 12 and bears upon the innersurface of the coating or sheet 10. On the tube 12 above the disk 7 is astud 21 to receive a connector on the other lead wire of the circuit.

ln order to hold the parts rigidly in posi-y t1 on and prevent" escapeof air around'the disk 7,-a'clamp is .provided for holding the `disksecurely and .pressing it down upon rthe iange ofthe tube 4, .This clampmay be 1n theform of ay metallicring 22, which,

'when not under restraint, assumes a position in which two diametricallyopposite points thereon are displaced in thedirection of the action ofthe ring from two other diametr1cally opposite points equally distanttherefrom. The ring 8 has two brackets 23 secured theretohatdiametrically oppositel pomts and the r1ng22 has notches y24 the-re- -1nthrough lwhichl the ends of the brackets in lhese notches 24 'are 'logfpomts of the clamping ring 2?, may pass when insertingthe clamp ring 1nyposition.' catedat the low axis.

The dished clamping ring 22 is then lowered within the ring8 until the notches 24 pass over the ends of the brackets 23 and thenthe ring is turned by means of, the handles 25 until the high points onthe ring are carriedunder the ends of the brackets 23 and' are vofozone. the opening in the'sup- 'I ily by merely disconnecting the wires,turning the clamping ring 22 throughv 90 so as to permit its withdrawalupwardly 4, around the tube 12 and then withdrawing Y one ormore of theparts 12, V 9, and 4."

lWhen the apparatus is in operation, air is supplied by the blower 13'through the tube 12, its flow being regulated by thel i .valve 16. Theair so supplied takes a tortuous path in flowing through the ozonizer.

lt passes. downwardly through the .tube 12 to the lower closed end ofthe cylinder 9 and then flows upwardly through ,the cylinder to theupper open .end thereof... Then it passes downwardly through the narrowspace between the cylinder and', the tube 4 to the lower open endofthe/tube 4. This end of tube 4 leads to the point of use of the ozoneand it may be contracted as may be deslred Vfor the purpose 4ofestablishing and maintaining a pressure. While'the air is Howvingthrough this passage, high .tension alternating current is supplied tothe wires -clonnected to the studs 19 and 21.- The cur rent flows fromthe stud 21 through tube 12 and -arm`20flto the film 10 onl the interiorofthe cylinder 9 and then passes across the gap vbetween the electrodes10 and 4 and then out through the contact 18 and stud 19. rllhe hightension passage across the gap between the electrodes 10 and 4 results nthe generation (if ozone and the current of air throughthisspace'carriesthe ozone generated "out through the discharge 'out- -let of theapparatus andv continually renewslthe supply of airfor the generationFurthermore, the urrent of ,air passing back and forth through theozonizer.
